TSK ball bushings are excellent in accuracy, rigidity and moment load. Straight shape standard type, flange type, housing type and self-aligning flange type are available. Single length bearing and high load capacity double length bearing are also standardized for each type. Especially, self aligning flange type (P.A.T) does not require precise square processing of the mounting surface, and the alignment is automatically adjusted and fixed by just mouting the bearing. This is a revolutionary linear bearing which enables a perfect ball alignment without troublesome machining of the mounting surface.
